T0 on whom it may concern.-

Beit known that I,LoU CAL. EDMUND, acitizen of the United States,residing at New York, in the county of'New York and State of New York,have invented new and useful Improvements in Tracing orDuplicatingPads,of which the following is a specification.

This invention relates toatracing or duplieating pad for makingimpressions in accordancewitha desired pattern on paper, leather, wool,cotton, silk, and other materials.

The object of the invention is to provide a simple, cheap, and efiicientconstruction of pad by which patterns may be readily and convenientlymarked on various materials and in which provision is made for securingthe essential parts in such manner as to permit of their easyapplication to a supporting-frame and their ready removal therefrom when0c casion requires.

With this and other objects in view the invention consists of thefeatures of construction, combination, and arrangement of partshereinafter fully described and claimed, reference being had to theaccompanying drawings, in Which Figure 1 is a perspective View of atracingpad embodying my invention, a portion being broken away to showthe arrangement of the pad proper and screen layer. Fig. 2 is across-section of the same, taken on line 2 2 of Fig. 1; and Fig. 3 is adetail section through one end of the frame, showing the manner ofsecuring the free edge of the screen layer.

The numeral 1 in the drawings represents a suitable inclosing andsupporting frame, the same being shown in the present instance as beingof'oblong rectangular form and comprising side pieces 2 and 3 and endpieces 4 and 5, suitably fastened together. The frame, however, maybe ofany other preferred form adapted for the purpose.

As shown,- the side pieces 2 and 3 and the end piece 4 are groovedaround their upper inner edges to form a recess 6 around three of thesides of the frame, the fourth side or end piece 5 having its uppersurface lying in the plane of the base-wall of the recess to form anentrance thereto, as hereinafter described. Supported bythe frame is atracing or duplicating pad 7, composed of cardboard, porous wood, orother suitable material, said pad being provided upon its upper surfacewith a coating of pigment 8, said pigment consisting of suitablecoloring-matter combined with sufiicient adhesive material to hold thepigment to the pad except when a portion of the same is loosened by amarking-wheel or similar tool. The edges of the pad contiguous to theside pieces 2 and 3 and the end piece 4 project suflicientlyinto therecess 6 to be firmly supported by the base-wall thereof, and betweenthese edges of the pad and the side walls of the recess are arrangedbeads or strips 9, which are permanently fastened to the frame by meansof tacks or like fastenings 10 passing downward through the strip andthe base-wall of the recessed portions 6. These strips limit the widthof the open portions of the recess 6 and properly serve as guides forthe pad 7, whose side edges fit sufficiently tight against the strips onthe side pieces 2 and 3 to normally prevent the pad from accidentallydropping out of the frame, but not with sufiicient friction to preventthe pad from being inserted. into the frame and withdrawn therefrom by asliding movement through the open space or entrance aflorded by thecut-away upper surface of the end piece 5, which, as before stated, liesin the plane of the base-wall of the recess 6, and

therefore forms a surface over which the pad 7 may be slid in applyingit to and removing it from the frame.

Arranged over the pigmented surface 8 of the pad 7 is a screen layer 11,composed of wire or other suitable mesh or reticulated material havingopen meshes .of suitable size to permit of the passage of the loosenedportions of the pigment therethrough for transfer to the surface of thematerial on which the pattern is to be duplicated. This layer issuperposed upon the pigmented surface in such manner that the meshes arenormally out of contact with said surface, and thus prevent the unevendistribution of the pigment and smearing or discoloration of thematerial to which the pattern is to be transferred. Three of the edgesof the screen layer 11 are secured to the side portions 2, 3, and 4 ofthe frame by arranging them between the side wall of the recess 6 andclam ping them thereagainst by the strips 9, which thus serve to holdthe screen layer in place, while forming guides for the pad 7 The otheror fourth edge of the screen 11 extends overupon the upper surface ofthe end piece 5, which, as before de scribed, is unprovided with a strip9 and instead of being permanently fastened to said end piece 5 isdetachably secured thereto by means of thumb-tacks or like securingdevices 12, which may be. readily withdrawn to free the said edge of thescreen, and thus permit of the ready insertion and removal of the pad7.-

In assembling the parts it will be understood that the frame is firstformed and the strips 9 placed in the recess 6, after which the screenlayer 11 is arranged in position with three of its side edges tuckeddown between the side walls of the recess and the strips 9 on the sideand end pieces 2, 3, and 4, after which the strips are adjusted to clampthe edges of the screen and then fastened in clamping position by thesecuringdevices 10. The pad 7 is then slid into place over the uppersurface of the end piece 5 and the free edge of the screen then tackeddown or secured to said end piece by the freely-detachable fastenings12.

In using the device the material to which the pattern is transferred islaid flatwise upon the screen 11, the pattern laid upon the uppersurface of the material, and a markingwheel or like device employed totrace the "outline of the pattern, the depression of the material by thesame causing the underlying portions of the pigment layer 8 to beloosened and transferred through the open meshes of the screen to thematerial in an obvious manner. If desired, the material to be marked maybe folded with oneof its folds lying upon the screen 11 and a similarpad arranged beneath its other or upper fold, a pattern laid upon theupper fold, and a tracing-wheel or marker employed to effect thetransfer in the manner described, the pressure causing the transfer ofa'portion of the pigment from each of the pigmented surfaces to the twofolds of the fabric, thus eflecting a double transfer. In this mannerseveral layers or folds of fabric or other material may be readily andconveniently marked.

It will be seen that my invention provides a simple, cheap, andconvenient device for the purpose described and that by confining theparts in the manner set forth in the supporting-frame-the pad 7 whendepleted of its coat= ing or pigment may be quickly removed by simplydetaching the securing devices 12 and sliding it outwardly over theupper surface of the end piece 5, after which a new pad may beconveniently inserted into position and the free edge of the screenlayer 11 secured by the fastenings 12 again to retain the pad in place.When it is desired to disassemble the parts of the device for anypurpose, this may be readily accomplished by first removing thefastenings 12 and then detaching the strips 9 by withdrawing theirfastenings 10, as will be readily understood.

While I have shown in the present instance a frame of oblong rectangularform composed of What I have hereinbefore termed side and end pieces, itWill of course be understood that I may use a square frame and that theparts 4: and 5 may properly be termed sides of the frame. With thisunderstanding I have set forth in the following claims a structure inwhich provision is made'for the convenient insertion and removal of thepad by securing the screen layer at three of its sides to the frame,leaving the fourth side free or detachably secured, so that it may bequickly adjusted to admit of the passage of the pad. Such anorganization is readily applicable to a square frame, and it will beunderstood that the claims are designed to cover the application of theinvention to a square, oblong, rectangular, or any other suitable formof frame in connection with which the described arrangement of the partsmay be employed.

Having thus described the invention, what is claimed as new is 1. Atracing or duplicating device comprising a frame, a pad having acoloring-pigment on its surface, said pad being supported upon andremovable through one side of the frame, and a screen layer over thepigment-carrying surface of the pad, said layer being permanentlysecured on three of its edges to the frame and having its other edgefreely detachable to permit removal of the pad.

2. A tracing or duplicating device comprising a frame having areceiving-recess and an entrance to said recess, a pad having acoloring-pigment on its surface, said pad being arranged in said recessand insertible and removable through said entrance, strips in the recessforming guides for the pad, and a screen layer over the pad having threeof its side edges clamped to the frame by said strips, the

other side edge being detachably secured to the base of the entrance toremovably confine the pad in place.

3. A tracing or duplicating device comprising a rectangular frame, threeof the sides of the frame being provided on their inner upper edges withgrooves forming a recess, the fourth side having an entrance to saidrecess, strips in the recess, a pad having three of its edges seated inthe recess and guided by said .strips and its other edge supported bythe wall of the entrance, a screen layer over the pad having three ofits side edges clamped by the strips against the wall of the recess, theother edge of the layer being arranged to overlie the wall of theentrance, and means for detachably securing the latter-named edge to thewall of the entrance to removably confine the pad in place.

In testimony whereof affix my signature in presence of two witnesses.
